I think that they were only offered for a limited run in just a few popular sizes. I pick up XX75 shafts whenever possible and for the right price, but I never pay more for the "odd" paterns (treebark,knotty birch,serpents,OA)so I really dont think that there is any "collector" premium on the price. They do make a much prettier arrow though than run of the mill GGs or camo hunters when capped and crested. I think I have a half dozen somewhere with my 2016s in case I pick up a bow that shoots that size.
